R22 replacement

[Phase8]

Is there a cheaper drop in replacement for R22 that will work in a walkin cooler?

I'm opting for DuPont's Isceon MO99 (R438A). While no available replacement refrigerants are true drop-ins, MO99 comes very close as it requires no oil change and will work well for replacing R22 in existing low, medium and high temperature systems.

It's cost is currently about 25% less than R22.

Here's a good video from DuPont:

MO99 is an easier retrofit as it doesn't require an oil change. If you've got a system where the compressor capacity is marginal, MO99 may not be the best choice. You will see a descrease in capacity using MO99 vs R-22.

It's best to check with the compressor manufacturer and see what the compressor capacity is going to be in the application you're considering for a conversion and see if there will be sufficient capacity.

R-407A, which requires POE oil, will be a better option capacity wise.

I have never done an oil change, is it difficult?

Nah.

Just pull the plug, let the oil drain all over the floor or roof, put the plug back in and add oil back in.
